3. Soft Front Panel

The soft front panel (SFP) for DRM Signal Generation allows engineers to quickly generate the

signals by selecting appropriate generation mode and other configurations. The default signal

generation mode of the SFP is Generate and Save Waveform in File and in this mode the generated

waveform is stored in a file.

3.1 MaxEye DRM Signal Generation SFP

The figure below shows the DRM Signal Generation SFP.

3.1.1 Generate and Save Waveform/ Generate and Play Waveform

Generate and Play waveform is used to generate DRM signal using hardware. Generate and Save

Waveform is used to generate the baseband IQ waveform and store in a file. For this mode

hardware is not required. The Play Waveform from File mode reads the DRM waveform from the

file created using the Generate and Save Waveform and then downloads the waveform to NI RFSG

Memory and then plays the waveform.


6

Use the Generate and Save Waveform mode

To generate and store the custom waveforms based on your test requirement.

To avoid generating the waveform at the beginning of your test every time. This reduces your

test starting time as some of the signal configuration will take longer to generate the waveform.

For generating the longer duration waveform as the RFSG memory size is limited.

For testing your receiver for continuous signal reception.

For receiver sensitivity measurement (BER) for longer duration.

Follow the procedure below to generate signals using these generation modes.

1. Select Waveform Format -> Generation Mode -> Generate and Save Waveform or

Generate and Play Waveform

2. Select Hardware Settings to configure the following parameters.


7

Note: - These settings need not to be configured if the chosen Generation Mode is Generate and

Save Waveform.

any, between the NI RF signal generator and the device under test. Positive values for this

property represent amplification, and negative values for this property represent attenuation.

Arb: Pre-filter Gain (dB) – Specifies the Arbitrary Waveform Generator (AWG) Pre-filter

Gain, in dB. The pre-filter gain is applied to the waveform data before any other signal

processing. Reduce this value to prevent overflow in the AWG interpolation filters. Other gains

on the NI-RFSG device are automatically adjusted to compensate for non-unity AWG pre-filter

gain.

Ref Clock Source – Specifies the source of the Reference Clock signal.

Frequency (Hz) – Specifies the Reference Clock rate, in Hertz (Hz).

Clk Output Terminal – Specifies the terminal where the signal will be exported..

4 How to configure parameters for Single Carrier/ Multiple

Carriers

The controls Carrier Configuration, DRM Configuration, Service Configuration and Impairments

are configured for each carrier. Hence the controls are given in an array where each element

corresponds to one carrier. Since the index value starts from 0, the index 0 corresponds to 1st

carrier, index 1 corresponds to 2nd

carrier and so on.

4.1 Single Carrier

For single carrier configuration, configure only index 0 of the above controls.

4.2 Multiple Carrier

For multiple carriers, use the index display to navigate through different elements and configure for

the required number of carriers. For N carriers, configure upto index N-1.
